Specification of Letters Patent No. 3,887, dated January 16, `184:5.

To all 'whom t may concern y 1 A j Be it known that I, LUKE HALE, of Hollis, in the State of New Hampshire, haveinvented a certain new and vuseful Improvement or Mode of Constructing the Endless Floors of Horse-Powers, of which thefollowing description and 'accompanying drawings, taken in connection,` constitute a 'full and exact specification.

Figure l of the aforesaid'l drawingsfrepll resents a top view of a horse power con-v structed on my improved principles. Fig. 2,

is a side elevation of the same. Fig. 3is. a`

view lof the inner side lofla part otone of the iron chains to which the floor boards are attached as will be hereinafter described-e and Fig. t is al view of the lower side ofVV such portion ofthe iron chain. `Fig.` 5 isa representation of the front` side of the rear portion of each vof `the .linksto which the floor boards are bolted. V.Fig.f6` is a repre# sentation of the rearside of the Vother portion of the last named link. Fig. `7 is a front, view of one of the other links, and Fig.` 8 is a rear View of the same. Fig. 9,is a bottom view of it and Fig. 1Q is a cross section" taken through the centerV of one of the bolts by which the floor board 0r boards areconnected to their respective links. Y Fig. 1,1 is an elevation of a change in form ot the invention which may be substituted for that herein particularly' described.

Each of the floor rboards A A bears at each of its ends on three of the links-viz., B, C, C, of the chain-that is to say wholly on the link B, immediately bolted to it and partly on the two other links (C, C,)". As

the chain is composed of such links put or joined together the one after the other as seenY in thedrawings, it'will be :sutlicient to` describe the particular mode of connecting three of these links together and to the end of the floor board above them, as well asthe improvement addedto the links to givey and maintain stability to the whole. The

link Bis composed of twojparts, viz.,g?9, c, each of which has `an ear (CZ of the one and `c of the other) projecting from yits inner surface near its upper edge and lapping over each other as seen in Fig. .l0 when the chain is completed, and each ear has a small rectangular `tenon or projection f,rupon.it,

which enters into a corresponding mort-isc or space Vcast in the opposite portion of the link. The rear portion (b), of the link has two 4tenons or studs h, 71 projecting or cast upon its top edge-the obj ect of thesame being to enter corresponding mortisesor apertures formedlin lthe' lower side vofthe end of the ioor board-'in order to prevent theA link from -turningilaterally upon'the board. Circular apertures z', i, are cast inthe inner rfaceof each portion'b, c, ofthe link in order l to receive lcorresponding projections '70, le,

cast vupon `the ends oiltheother:` links as seen in ther drawings. Each of the other links has a tooth fu,- cast uponits frontside,'-which 's (tooth) .renters intolthe lspace-between 1 the f D, E, around'which the endless floor travels.

The rear" portion 1703. the center link is Vmuch larger than the adjacent links C, C, `ory the'lportfion c, orllnother wordseach end of it'A has a Vbearing `0, oris extended toward the central part of the rear side of the link C, and'iscurved upward .or Votherwise suitablyformed so asto rest lupon a seat or `pro`y j ection p, extending from and cast upon the `.inner sideof the link C. `When the several -linksand portions composing the same AVand the floor boards are put together they are` all rmlyf-heldor conined to each other by one screw bolt, g, which is passed through.`

through theend of the floor board.`

Instead of having the seats p, upon the links C, T, projections or bearings may be cast upon and riseabove them as seen at G H, Fig. 1l, and may rest against a block F bolted to the end board A.

of thetop of the floorv `the ears (Z and e of the center link, and

` From the aboveit will be seen thatV when n the links of the chain are brought intoa straight line with each other, they bear upon one another independent of the ioor boards andV form one inflexible bar, as it were,lto

`support the iioor boards and the horse, 'thus preventing to a great degree the wear which f lwould bey occasioned by the floor boards resting land bearing upon the linksC, C,

k'i' E without seats being applied to said linksand-projections upon the rear part of Vthe'l f link B, torestupon such seats.

v `Hav-ing thus set forthvmy invention I:

shall claim-'- l The 'mode oflfrmly uniting together by y j A so i one screw bolt the severa-1 parts of the three In testimony whereof, I have hereto set links B, C, C--and the oor board-viz, by my signature this third day of December l0 a combination of ears, d, e, cast upon the A. D. 1844.

inner sides of the two portions of the link B', so as to lap over each other and permit7 LUKE HALE the screw boltto pass through them and Witnesses:
